I've noticed that I remember events based on where I was living, where
I was working, or what school I was in, or what grade if it's a
childhood event (I went to a small school where there was one grade per
classroom). I don't remember specific years or ages associated with
the events but I can make an educated guess. I have a friend, who's
not autistic but remembers an enormous amount of historical/politcal
facts and who can also easily remember what year something personal
happened - but he has a problem remembering what he said two minutes
ago. I find that really odd.

Joseph Ledoux's "Emotional Brain" has information on how we form
memories though it may not be exactly what you (the original poster)
are looking for. "The User's Guide to the Brain" (by John Ratey, I
think) is really good and it probably had some things on memory.
